What was advertised in a revolutionary American newspaper 250 years ago today?

“The Utility of such a Map must appear obvious to every Officer who understands the nature of Actual Service.”
On July 9, 1776, Dunlap’s Maryland Gazette became the first newspaper outside of Philadelphia to publish the Declaration of Independence. A week later, its first advertisement promoted a map that the printer considered essential for officers now that the aims of the war had shifted from achieving a redress of grievances to achieving independence from Great Britain.
An introduction that indicated a “MAP of New-York, Staten Island, part of Long-Island, and New-Jersey” would be ready for sale in a few days emphasized that the map was “absolutely necessary for every Officer under Marching orders for New-York.” As they gathered equipment and supplies in advance of departing to defend New York, officers needed to outfit themselves with a map that “delineated, the situation of the British Forces now on Staten-Island” as well as the “different Batteries thrown up for the defence of the Continental troops in those parts.” Just in case the target audience had not grasped the appeal made in the introduction, the advertisement concluded with an assertion that the “Utility of such a Map must appear obvious to every Officer who understand the nature of Actual Service.” Not purchasing the map, the advertisement suggested, amounted to a dereliction of duty.
The advertisement, without revision, ran for two more weeks, promising the imminent publication of the map even after the time that it “will be ready for Sale” based on when the notice first appeared in the newspaper. The printer did not follow up with another advertisement announcing the publication and availability of the map. Was that because he did not consider such an advertisement necessary … or because plans for publishing the map did not work out? I cannot find an extant copy of the map described in the advertisement, but copies of a map with a similar (but much lengthier) title are in the collections of several historical societies and research libraries: A Plan of New York Island, with part of Long Island, Staten Island & East New Jersey, with a Particular Description of the Engagement of the Woody Heights of Long Island, between Flatbush and Brooklyn, on the 27th of August 1776 between Hist Majesty’s Forces Commanded by General Howe and the Americans under Major General Putnam, Shewing also the Landing of the British Army on New-York Island, and the Taking of the City of New-York &c. on the 15th of September Following, with the Subsequent Disposition of Both the Armies. William Faden published that map in London. It certainly was not the map from the advertisements in Dunlap’s Maryland Gazette in July 1776 … yet the possibility exists that the engraver consulted (and updated) an American map that depicted the same area when creating the map of those historic battles.
